  The action column 123d stores information for specifying an operation corresponding to the detection value detected by the sensor 101 specified by the sensor column 123c when specified by the time column 123b. In the present embodiment, when a detection value having no action corresponding to the action table 123a is detected, a character string of “unclear” is stored.

  Returning to FIG. 2, the work dictionary information storage area 124 stores information for specifying a work corresponding to a combination of actions.

  The NO column 124c stores information for specifying the order of operations stored in the operation column 124d described later. Here, in the present embodiment, information for specifying a natural number starting from “1” is stored as information for specifying the order of operations. However, the present invention is not limited to this mode.

  In the operation column 124d, information for specifying an operation constituting the work specified in the work column 124c is stored.

  Returning to FIG. 2, the work information storage area 125 stores information for specifying the operation corresponding to the measurement value measured by the sensor 101 and the work.

  For example, in the present embodiment, a work table 125a illustrated in FIG. 7 (schematic diagram of the work table 125a) is stored.

  The work table 125a includes a time field 125b, a sensor field 125c, an action field 125d, and a work field 125e.

  The operation column 125d stores information for specifying an operation corresponding to the detection value detected by the sensor 101 specified by the sensor column 125c when specified by the time column 125b. Here, in this column, information corresponding to the operation column 123d of the operation table 123a is stored.

  The work column 125e stores information for specifying a work corresponding to the combination of operations specified in the operation column 125d. Here, in the present embodiment, the work name is stored as information for specifying the work, but the present invention is not limited to such a mode. In the present embodiment, columns corresponding to operations without work corresponding to the work dictionary 124a are left blank.

  Returning to FIG. 2, the environment information storage area 126 stores information for specifying the worker's environment.

  For example, in the present embodiment, as information for specifying the correspondence relationship between the worker and the sensor 101, the correspondence relationship table 126a as shown in FIG. 8 (schematic diagram of the correspondence relationship table 126a), the worker group organization is specified. As such information, a group organization table 126f as shown in FIG. 9 (schematic diagram of the group organization table 126f) is stored.

  As shown in FIG. 8, the correspondence table 126a includes an operator column 126b, a sensor type column 126c, and a sensor ID column 126d.

  The worker field 126b stores identification information for identifying the worker (in this embodiment, the name of the worker).

  The sensor type column 126c stores information for specifying the type of sensor attached to the worker specified in the worker column 126b.

  The sensor ID column 126d stores information for specifying a set of sensors attached to the worker specified by the worker column 126b.

  As shown in FIG. 9, the group organization table 126f includes a group column 126g and an operator column 126h.

  The group column 126g stores identification information (in this embodiment, a group name) for identifying a group of workers.

  The worker column 126h stores information for identifying identification information (in this embodiment, the name of the worker) for identifying workers belonging to the group specified by the group column 126g.

  Returning to FIG. 2, the control unit 130 includes a measurement information management unit 131, an operation analysis unit 132, a work analysis unit 133, and an output information generation unit 134.

  The measurement information management unit 131 performs a process of storing measurement values received from each sensor 101 in the measurement table 121a via the communication unit 142 described later.

  The measurement information management unit 131 stores a correspondence relationship between the sensor ID of each sensor 101 and an ID for identifying a set of a plurality of sensors 101A, 101B, and 101C attached to the worker. The ID corresponding to the sensor ID attached to the measurement value received from each sensor 101 is stored in the ID column 121c of the measurement table 121a.

  The motion analysis unit 132 performs processing for specifying an operation corresponding to the measurement value from the measurement value stored in the measurement table 121a.

  Specifically, the motion distribution base 132 extracts the measurement value stored in the measurement table 121a at each time, performs Fourier transform on the extracted measurement value, and converts it into a frequency component. Here, in the present embodiment, each of the detection values acquired from the left hand, right hand, and left foot sensors 101 is Fourier-transformed.

  Here, Fourier transform is a method of signal analysis, and converts measurement data into weight parameters for each frequency. In the present embodiment, since the measurement value is digitized and processed, FFT is used as a frequency analysis for the digital value.

  FIG. 10 (schematic diagram showing the result of Fourier transform of the measurement value) shows a schematic diagram of the result of Fourier transform of the information stored in the measurement table 121a shown in FIG.

  Then, the motion analysis unit 132 identifies a record in which the value Fourier-transformed for each time and the values stored in the left hand column 122c, the right hand column 122d, and the left foot column 122e of the motion dictionary table 122a match or are similar. The operation stored in the operation column 122b of the identified record is determined as the operation at the time.

  Here, the motion analysis unit 132 performs Fourier transform on the detected values detected from the left hand, right hand, and left foot for each time, respectively, in the left hand column 122c, right hand column 122d, and left foot column 122e of the motion dictionary table 122a. By specifying a record that matches or is similar to the value stored in, the movement of the worker can be identified from the movements of the worker detected by the plurality of sensors. Become.

  Whether or not they are similar is generally the least square method in which the least square sum of the difference between the values in each column is selected, but is not limited to such a method.

  Also, in the judgment of coincidence, it is judged that a match is found if a match is found in a predetermined frequency range (for example, a range excluding at least one of a specific high frequency portion and a low frequency portion). It may be.

  Note that the motion analysis unit 132 determines that the value Fourier-transformed for each time and the values stored in the left hand column 122c, the right hand column 122d, and the left foot column 122e of the motion dictionary table 122a do not match or are similar to each other. The operation at the time is determined to be unknown.

  Then, the motion analysis unit 132 generates the motion table 123a as illustrated in FIG. 5 by storing the motions searched as described above for each time, and stores the motion table 123a in the motion information storage area 123.

  The work analysis unit 133 performs a normalization process on the information specifying the operation stored in the operation table 123 a stored in the operation information storage area 123.

  The normalization process here is a process in which the parts where the same operation is continued are combined into one operation, and the part storing the character string “unknown” is deleted. FIG. 11 shows a schematic diagram of an operation table 123a ′ after normalization processing obtained by normalizing the operation table 123a shown in FIG.

  Next, the work analysis unit 133 determines whether any combination of actions (arbitrary combination in time series) stored in the operation table 123a ′ after normalization processing is stored in the action column 124d of the work table 124a. Judge whether or not.

  Then, the work analysis unit 133 adds a new work column 125e to the normalized operation table 123a ′ and combines the operations stored in the operation column 123d of the operation table 123a ′. Information identifying the work is extracted from the work field 124e of the record whose action combination is stored in the action field 124d of the work dictionary table 124a, and is stored in the corresponding work field 125e, thereby generating the work table 125a. .

  The work analysis unit 133 stores the work table 125a generated in this way in the work information storage area 125.

  The output information generation unit 134 accepts input of search conditions via the input unit 140 described later, extracts information corresponding to the input search conditions from the work information storage area 125, and puts it in a predetermined format. Process to output.

  Here, in the present embodiment, the input of the worker's name or group name is accepted via the input unit 140, and the operations of the worker included in the group specified by the worker name or group name and the work And the process which outputs the information which specifies these operation | movement and operation | work time to the output part 141 is performed.

  In addition, when the worker's name is input via the input unit 140, the output information generation unit 134 acquires the sensor ID corresponding to the worker from the correspondence table 126a, and acquires the acquired sensor ID. Are extracted from the work table 125a.

  Further, when a group name is input via the input unit 140, the output information generation unit 134 extracts the names of workers belonging to the group from the group organization table 126f, and corresponds to the extracted workers. The sensor ID is acquired from the correspondence table 126a, and the time, operation, and work corresponding to the acquired sensor ID are extracted from the work table 125a.

  FIG. 12 is a schematic diagram of output information 134 a output from the output information generation unit 134 to the output unit 141.

  The output information 134a includes a time column 134b, a sensor column 134c, a work column 134d, a worker column 134e, and a group column 134f. Information extracted by the output information generation unit 134 and information related to the information Is stored.

  The input unit 140 receives input of information.

  The output unit 141 outputs information.

  The communication unit 142 transmits and receives information via the antenna 143.

  The work information processing apparatus 110 described above includes, for example, an external storage such as a CPU (Central Processing Unit) 161, a memory 162, and an HDD (Hard Disk Drive) as shown in FIG. 13 (schematic diagram of the computer 160).

The input unit 140 can be realized by the CPU 161 using the input device 166, and the output unit 141 can be realized by the CPU 161 using the output device 167. The communication unit 142 can be realized by the CPU 161 using the communication device 168.

  The predetermined program is downloaded from the storage medium 164 via the reading device 165 or from the network via the communication device 168 to the external storage device 163, and then loaded onto the memory 162 and executed by the CPU 161. You may do it. Alternatively, the program may be directly loaded on the memory 162 from the storage medium 164 via the reading device 165 or from the network via the communication device 168 and executed by the CPU 161.

  FIG. 14 is a flowchart showing processing in the work information processing apparatus 110.

  First, the measurement information management unit 131 of the work information processing apparatus 110 receives a measurement value from each sensor 101 via the communication unit 142 (S10).

  Then, the measurement information management unit 131 stores the received measurement value in the measurement table 121a stored in the measurement information storage area 121 (S11).

  Next, the motion analysis unit 132 of the work information processing apparatus 110 synthesizes the values obtained by Fourier transforming the measurement values stored in the measurement table 121a using the values obtained from the plurality of sensors 101 attached to one worker. Then, the operation corresponding to the synthesized value is specified from the operation column 122b of the operation table 122a (S12). The motion analysis unit 132 stores the identified motion in the time-sequential motion table 123a, and stores the motion table 123a in the motion information storage area 123.

  Here, the processing in the motion analysis unit 132 may be performed periodically, for example, once a day, or an analysis instruction specifying a time interval to be analyzed via the input unit 140. You may perform by receiving an input.

  Next, the work analysis unit 133 of the work information processing apparatus 110 normalizes the information stored in the action table 123a, and the work dictionary stored in the work dictionary information storage area 124 corresponding to the normalized action. It is specified from the work column 124b of the table 125a (S13). The work analysis unit 133 stores the identified work and the operation corresponding to the work in the time-sequential work table 125a, and stores the work table 125a in the work information storage area 125.

  Then, the output information generation unit 134 of the work information processing apparatus 110 receives input of search conditions such as a worker name and a group name via the input unit 140 (S14), and receives information corresponding to the received search conditions as work information. The data is extracted from the work table 125a stored in the storage area 125, and output to the output unit 141 in a predetermined output format (S15).

  FIG. 15 is a flowchart showing processing in the operation analysis unit 132 of the work information processing apparatus 110.

  First, the motion analysis unit 132 performs a Fourier transform on the measurement values stored in the measurement table 121a stored in the measurement information storage area 121 (S20).

  Next, the motion analysis unit 132 synthesizes the values Fourier-transformed in step S20 obtained from the sensor 101 attached to one worker and arranged in the order of left hand, right hand, and left foot (S21). . That is, the combination of these values is made into one data string by arranging the values obtained by Fourier transform from the measurement values obtained from the sensor 101 attached to one worker in order of the left hand, the right hand, and the left foot.

  Next, the motion analysis unit 132 identifies the motion corresponding to the value synthesized in step S21 from the motion dictionary table 122a stored in the motion dictionary information storage area 122 (S22).

  Then, the motion analysis unit 132 generates the motion table 123a and stores it in the motion information storage area 123 by extracting the motions identified in step S22 and arranging them in time series (S23).

  FIG. 16 is a flowchart showing processing in the work analysis unit 133 of the work information processing apparatus 110.

  First, the work analysis unit 133 reads the operation table 123a stored in the operation information storage area 123 (S30).

  Next, the work analysis unit 133 deletes a record stored as “unknown” in the operation column 123d of the read operation table 123a, and records that continuously store the same operation into one record. By summing up, the information is normalized (S31).

  Then, the work analysis unit 133 stores work corresponding to the continuation of a plurality of actions stored in the action column 123d of the normalized action table 123a as a work dictionary table 124a stored in the work dictionary information storage area 124. A work table 125a in which operations and work are arranged in time series is generated and stored in the work information storage area 125 (S33).

  In the embodiment described above, the motion analysis unit 132 Fourier-transforms the measurement value. However, the present invention is not limited to such a mode. For example, at least one of the predetermined values before and after a specific time is determined. The average value of the measured values in the interval is taken as the value at the specific time from the motion dictionary table (the average value is also stored in the left hand column, right hand column and left foot column of the motion table). May be extracted. By performing such processing, it is possible to weaken the fine acceleration change, that is, the vibration component, and only the data indicating the movement of the large change remains, and an appropriate action can be specified.

  In the embodiment described above, the motion analysis unit 132 specifies the motion most similar to the Fourier-transformed value in step S22 of FIG. 15, but is limited to this mode. For example, it is also possible to specify a plurality of candidate actions in descending order of similarity and select appropriate candidates by matching the work dictionary table 124a using the plurality of candidate actions. it can.

  For example, if the motion candidate at a certain point in time as a result of motion analysis is “screw” or “push” and the motion before and after is “walking” or “attachment”, the motion sequence is “walking” “screw” “attachment” ”Or“ walking ”,“ pushing in ”, and“ attaching ”. Here, if there is a work corresponding to one of the candidates in the work dictionary table 124a, it can be determined that there is a high possibility that the column of these actions is a work exists.

  As described above, in the present invention, a plurality of candidates may be handled, and a comprehensive analysis may be performed by linking the operation analysis and the work analysis.

  Further, in the present embodiment, the analysis of the operation and the analysis of the work are performed from the measurement value, but the present invention is not limited to such a mode, and for example, corresponds to the work column and the work column. By providing a business dictionary table storing business, it is possible to analyze a business corresponding to a work sequence (desirably normalized as in the above embodiment) specified by the work analysis unit 133.

  As shown in FIG. 23, the correspondence table 326a includes an operator column 326b, a sensor type column 326c, and a sensor ID column 326d.

  The worker column 326b stores identification information (in this embodiment, the name of the worker) for identifying the worker.

  The sensor type column 326c stores information for specifying the type of sensor attached to the worker specified in the worker column 326b. Here, in the present embodiment, the acceleration sensor or the position sensor is stored.

  In the sensor ID column 326d, information for specifying the set of sensors 101 or the position sensor 302 attached to the worker specified in the worker column 326b is stored.

  Returning to FIG. 21, the position specifying information storage area 328 stores information for specifying a space (location) corresponding to the detection value detected by the position sensor 302.

  For example, in the present embodiment, a position specifying table 328a as shown in FIG. 24 (schematic diagram of the position specifying table 328a) is stored in the position specifying information storage area 328.

  As illustrated, the position specifying table 328a includes a room number column 328b, an x range column 328c, a y range column 328d, and a z range column 328e.

  The room number column 328b stores information for specifying the room in which work is performed. Here, in the present embodiment, the room number assigned to each room is stored as the information for specifying the room in which the work is performed. However, the present invention is not limited to this mode.

  The x range column 328c stores information for specifying the latitude range of the room specified in the room number column 328b. Here, in the present embodiment, the minimum value (min) and the maximum value (max) of the latitude of the room specified in the room number column 328b are stored.

  Returning to FIG. 21, in the position information storage area 329, information for specifying the space (place) where the worker was present is stored based on the detection value detected by the position sensor 302.

  For example, in the present embodiment, a position table 329a as shown in FIG. 25 (schematic diagram of the position table 329a) is stored in the position information storage area 329.

  As illustrated, the position table 329a stores a time field 329b, a sensor field 329c, and a room field 329d.

  The time column 329b stores information for specifying the time when the detection value transmitted from the position sensor 302 is received.

  The sensor column 329c stores information for identifying the position sensor 302 (here, the ID of the position sensor 302).

  The room column 329d stores information for specifying the space (location) indicated by the detection value detected by the position sensor 302 specified by the sensor column 329c at the time specified by the time column 329b. In this column, the detection value detected by the position sensor 302 is stored in the room number column 328b corresponding to the records included in the x range column 328c, the y range column 328d, and the z range column 328e of the position specifying table 328a. Stored room number is stored.

  Returning to FIG. 21, the control unit 330 includes a measurement information management unit 331, an operation analysis unit 132, a work analysis unit 133, an output information generation unit 334, and a position analysis unit 335.

  The measurement information management unit 331 performs a process of storing the measurement values received from the sensors 101 and the position sensor 302 via the communication unit 142 described later in the measurement table 121a and the position measurement table 321h.

  The position analysis unit 335 performs processing for specifying the space (place) where the worker was present from the detection value detected by the position sensor 302.

  Specifically, the position analysis unit 335 extracts information specifying the longitude, latitude, and altitude stored in the x column 321k, the y column 321l, and the z column 321m of the position measurement table 321h for each time, The information specifying the extracted longitude, latitude and altitude specifies the records included in the longitude range, latitude range and altitude range specified in the x range column 328c, y range column 328d and z range column 328e of the position specifying table 328a. Then, the room number stored in the room number column 328b of the record is extracted.

  Then, the position analysis unit 335 stores the extracted room number, the ID of the position sensor 302, and information specifying the time detected by the position sensor 302 in the time column 329b, the sensor column 329c, and the room column 329d. Thus, the position table 329a is generated and stored in the position information storage area 329.

  The output information generation unit 334 receives input of search conditions via the input unit 140, extracts information corresponding to the input search conditions from the work information storage area 125 and the position information storage area 329, and is determined in advance. Process to output in the specified format.

  Specifically, the output information generation unit 334 displays a search condition input screen 351 as shown in FIG. 26 (schematic diagram of the search condition input screen 351) on the output unit 141, for example, via the input unit 140. It accepts input of necessary search conditions and output forms, performs a search with the input search conditions, and outputs with the input output form.

  As illustrated, the search condition input screen 351 includes a NO column 351a, an item column 351b, a search condition column 351c, an axis column 351d, and a value column 351e.

  An identification number for identifying each item is stored in the NO column 351a.

  The item column 351b stores information for specifying an item to be selected in the search condition column 351c, the axis column 351d, or the value column 351e.

  The search condition column 351c accepts input of conditions for performing a search from the work information storage area 125 and the position information storage area 329.

  Here, the search condition column 351c is provided with a selection column 351f and an input column 351g. Then, in the selection column 351f, an instruction to select via the input unit 140 is input (checked), and the search target is input to the input column 351g, so that the output information generation unit 334 Information corresponding to the retrieved condition is extracted from the work information storage area 125 and the position information storage area 329.

  When the item column 351b is “date and time”, the start date and time and the end date and time for searching are input to the input column 351g.

  When the item field 351b is “place”, a work place (room number) is input as a search target in the input field 351g.

  When the item column 351b is “worker / group”, the worker name or group name is input to the input column 351g as a search target.

  When the item column 351b is “tool / equipment”, a tool name or facility name is input to the input column 351g as a search target.

  For example, the operation specified in the operation dictionary table 122a or the operation specified in the work dictionary table 124, such as knowing that an electric screwdriver is used when performing screw operation and screwing work, is a specific tool. When using, work and operation can be understood and output by the corresponding tool. In addition, when a specific facility is used, a place where such a facility is arranged can be identified.

  Therefore, for example, by storing a table in which the tool is associated with the operation or work in the storage unit 320, the operation or work is specified from the tool specified in the input field 351g, and the work table 125a is stored. Can be searched.

  Further, by storing a table in which the facility and the room number are associated with each other in the storage unit 320, the position table 329a can be searched.

  In addition, data representing tools and equipment is included in work instruction data for instructing work of an operator, and such data is input via the input unit 140 and stored in the storage unit 320. The output information generation unit 334 can search the worker's work, work time, and the like from tools and equipment.

  When the item column 351b is “target product”, the name of an article (manufactured product, transported product, etc.) to be worked is input to the input column 351g as a search target.

  For example, the operation specified in the operation dictionary table 122a or the operation specified in the work dictionary table 124 targets a specific article, such as when the screw operation or screwing operation is performed, the target product is known to be a screw. If there is, the work or operation can be specified by the input target product. Further, when producing a plurality of articles, since each production place (room number) is often a specific place, the place (room) can be specified by the input target product.

  Therefore, for example, by storing a table in which the object is associated with the action or work in the storage unit 320, the action or work is identified from the object identified in the input field 351g, and the work is performed. The table 125a can be searched.

  Further, by storing a table in which the object and the room number are associated with each other in the storage unit 320, the position table 329a can be searched.

  When the item field 351b is “work type”, a work name is input to the input field 351g as a search target.

  When the item column 351b is “required time of work”, a character string such as “short”, “standard”, or “short” as a search target is input to the input field 351g.

  Here, the time required for work is the time from the start time to the completion time of a specific work. Since the work table 125a is associated with data for specifying a time for an operation or a work, the time required for the work can be obtained as a difference between the completion time and the start time. When it is determined in the work table 125a that a plurality of works are continuously performed, the time required for the work can be obtained as a difference between the start time of the next work and the start time of the target work. .

  Then, by classifying the time required for the work into “short”, “standard”, or “short” with a predetermined threshold value, it is possible to specify the work classified into each.

  When the item column 351b is “work result amount”, a character string such as “small”, “normal”, or “large” as the search target is input to the input column 351g.

  Here, the work result amount is the amount of work performed at the input time. It is expressed as a numerical value indicating how many units have been assembled in the case of assembly work and how many pieces have been transported in the case of transport work. This can be calculated by storing the number output in the actual work for each work in advance in the storage unit 320 per work time.

  By storing the number of actual output in this way, the work result amount is classified as “low”, “normal”, or “high” according to a predetermined threshold value. It is possible to identify work classified as

  When the item column 351b is “efficiency”, a character string such as “bad”, “normal”, or “good” of the work efficiency is input to the input column 351g as a search target.

  Efficiency is the result of converting work output per fixed number of people or fixed time. Usually, a value such as per person or per hour is often used. In the embodiment of the present invention, the amount of work results is obtained by dividing the number of workers engaged and the time required for the work. In some cases, the time required for one operation, which is the reciprocal of this value, may be used.

  Further, when one worker performs a plurality of operations, a plurality of operations can be expressed by combining the number of operations A and the number of operations B in the time input as the work efficiency. Furthermore, a weight can be given to each work in advance, and a total index can be calculated and used by adding those times multiplied by the respective times. The number of executions from which these indexes are calculated can be obtained as the number of operations extracted by analyzing the measurement data.

  By classifying the efficiency calculated in this way into “bad”, “normal”, or “good” with a predetermined threshold value, it is possible to specify the work classified into each.

  When the item column 351b is “variation”, a character string such as “small”, “normal”, or “large” as the search target is input to the input column 351g.

  The variation is a difference in efficiency of workers belonging to the group depending on a person, a difference due to time, and the like, and is represented by a set of numerical values, a standard deviation, or the like.

  Identifying the group (operator) classified into each by classifying the variation obtained in this way into “small”, “normal”, or “large” with a predetermined threshold. Can do.

  In the axis column 351d, selection of an axis when the value selected in the value column 351e described later is displayed on the coordinates is accepted. In other words, by inputting an instruction to select via the input unit 140 to the axis column 351d corresponding to the item specified in the item column 351b (by checking), the selected item is displayed on the axis. Is done.

  Here, the axis column 351d includes a horizontal axis column 351h and a vertical axis column 351i, and an item can be selected in each column.

  Specifically, when the item specified in the axis field 351d is “date and time”, the value of the axis is determined at a predetermined time interval from a predetermined origin position in coordinates.

  When the item specified in the axis field 351d is “place”, a predetermined work place (room number) is arranged from a predetermined origin position in coordinates to a predetermined position.

  When the item specified in the axis field 351d is “worker / group”, the respective worker names or group names are arranged from the predetermined origin position in the coordinates to the predetermined position.

  When the item specified in the axis field 351d is “tool / equipment”, each tool name or equipment name is arranged from a predetermined origin position in coordinates to a predetermined position.

  When the item specified in the axis field 351d is “target product”, the name of an article (manufactured product, transported product, etc.) to be worked from a predetermined origin position in coordinates to a predetermined position. Is placed.

  When the item specified in the axis field 351d is “work type”, a predetermined work name is input from a predetermined origin position in coordinates to a predetermined position.

  When the item specified in the axis column 351d is “work required time”, “work result amount”, “efficiency”, or “variation”, a predetermined classification from a predetermined origin position in coordinates is performed. Are arranged at predetermined positions.

  The value column 351e accepts selection of a value to be displayed at the coordinates specified in the axis column 351d. That is, by inputting an instruction to select via the input unit 140 into the value column 351e corresponding to the item specified in the item column 351b (by checking), the item corresponds to the selected item. The value is displayed on the coordinates specified in the axis field 351.

  Returning to FIG. 21, the output information generation unit 334 searches the work table 125 a and the position table 329 a according to the search condition input in the search condition column 351 c of the search condition input screen 351, and calculates a value from information that matches the search condition. A value specified in the column 351e is extracted, and an output screen for displaying the extracted value at the coordinates specified in the axis column 351d is generated and output to the output unit 141.

  For example, FIG. 27 is a schematic diagram of the output screen 352.

  In the output screen 352, “date and time” and “work type” are selected in the search condition column 351c, “9:00 to 17:00” and “assembly” are input in the respective input columns 351g, and the side of the axis column 351d. In this example, “place” is selected in the axis column 351h and the vertical axis column 351i, and “date and time” and “worker / group” are selected in the value column 351e.

  For example, data obtained by performing assembly work between 9:00 and 17:00 specified as a search condition is extracted from the work information storage area 125 and the position information storage area 329, and the horizontal axis column 351h and the vertical axis column 351i. In the form of a two-dimensional map based on the location specified in, the date and time specified as the value column and the worker / group value (here, the number of people) are displayed. FIG. 27 shows a two-dimensional map in which a total of 10 rooms are lined up by five rooms across a passage, and each room was engaged in assembly work for each time between 9:00 and 17:00. The number of people is displayed.

  Thus, when “place” is selected in the horizontal axis field 351h and the vertical axis field 351i of the axis field 351d, the value is displayed on the two-dimensional map.

  The work information processing apparatus 310 described above can be realized by a general computer 160 as shown in FIG.

  For example, the storage unit 320 can be realized by the CPU 161 using the memory 162 or the external storage device 163, and the control unit 330 loads a predetermined program stored in the external storage device 163 into the memory 162. The input unit 140 can be realized by the CPU 161 using the input device 166, and the output unit 141 can be realized by the CPU 161 using the output device 167. The communication unit 142 can be realized by the CPU 161 using the communication device 168.

  The predetermined program is downloaded from the storage medium 164 via the reading device 165 or from the network via the communication device 168 to the external storage device 163, and then loaded onto the memory 162 and executed by the CPU 161. You may do it. Alternatively, the program may be directly loaded on the memory 162 from the storage medium 164 via the reading device 165 or from the network via the communication device 168 and executed by the CPU 161.

  FIG. 28 is a flowchart illustrating output screen generation processing in the output information generation unit 334.

  First, the output information generation unit 334 outputs a search condition input screen 351 as shown in FIG. 26 to the output unit 141, and accepts input of search conditions via the input unit 140 in the search condition input field 351c (S40). .

  Next, the output information generation unit 334 accepts selection of items that become the horizontal axis and the vertical axis in the axis input field 351d of the search condition input screen 351 (S41).

  Next, the output information generation unit 334 accepts selection of an item to be an output value in the value input field 351e of the search condition input screen 351 (S42).

  Next, the output information generation unit 334 searches for the necessary data by searching the work table 125a and the position table 329a based on the search condition input in step S40 (S43).

  Next, the output information generation unit 334 rearranges the data searched in step S43 according to the items of the horizontal axis and the vertical axis input in step S41 (S44).

  Next, the output information generation unit 334 calculates a value to be output based on the received output value item input in step S42 (S45).

  Then, the output information generation unit 334 generates an output screen by arranging the values calculated in step S45 on the coordinates rearranged in step S44, and outputs the output screen to the output unit 141 (S46).

  Since the output screen generation in the output information generation unit 334 is performed in such a procedure, the search condition, axis, and value items specified on the search condition input screen 351 are independent, and various combinations can be accepted. It is.

  For example, FIG. 29 is a schematic diagram of the display screen 353 when the vertical axis represents the group name, the horizontal axis represents the room number, and the value is the date / time and the worker.

  FIG. 30 is a schematic diagram of the display screen 354 when the vertical axis represents time, the horizontal axis represents the room number, and the value represents the work type and the worker.

  FIG. 31 is a schematic diagram of a display screen 355 in which the vertical axis is the operator, the horizontal axis is the location, and the value is efficiency. Here, in FIG. 31, the efficiency values are plotted, and the plotted values are connected by a straight line.

  FIG. 32 is a schematic diagram of a display screen 356 when the vertical axis represents the group name, the horizontal axis represents the date and time, and the value represents the work result amount.

  In the third embodiment, the display screen as described above is output to the output unit 141. However, the present invention is not limited to this mode.
